A Florida father, faced with a devastating choice, shot and killed his older son in order to save his younger child after the brothers got into a violent fight over a game of pool Sunday, police said.

Police received a 911 call at 5:47 a.m. from a woman, identified as Marie Maloney, who said her son, Joseph Maloney, 30, was acting irrational and needed to be “Baker Acted” at their Stuart home in The Florida Club, Martin County Sheriff William Snyder said in a news conference. The mother was referring to the Florida Mental Health Act that allows officials to involuntarily examine a person showing signs of possible mental illness.

“It was an extremely violent scene,” Snyder said.

Before deputies arrived at the home, however, Marie called 911 again. This time, she said her husband, John Maloney, shot Joseph after the 30-year-old got into a violent altercation with his 26-year-old brother, James Maloney.

The couple later told police their sons had been drinking when an argument over a billiards game escalated.

Joseph placed James in a chokehold while holding a “rather large butterfly knife” over his head, police said. The father verbally intervened in an effort to get his older son to release his grip, but to no avail.

The couple said they heard their younger son pleading to his sibling to let go and saying he couldn’t breathe, and once James began to lose consciousness, John fired his revolver, striking Joseph several times.

Snyder said Joseph had been acting irrationally in the hours before the deadly shooting. At one point, Joseph attacked a door with a machete while his parents locked themselves in the bedroom. James then intervened and attempted to keep his brother calm and away from their parents, according to police.

John Maloney will not face charges following the shooting because evidence and family witness statements showed "Mr. Maloney believed that the use of deadly force was necessary to prevent the death or great bodily injury to his younger son,” Snyder said, adding the father is “absolutely shattered” after shooting his son.

The Maloneys told investigators Joseph had been under a great deal of stress due to upcoming court action related to a 2015 DUI manslaughter case. Joseph was driving the opposite direction when he crashed his vehicle head-on with another car, killing high school football coach Cristopher D. Harrison in May 2015, TCPalm reported.

The 8-year-old saved up $250 from the tooth fairy, birthdays, Christmas and allowance to give to the homeless in Pensacola, Fla. – and he has no plans to stop there.

“One morning I woke up with a yearning for change in the world and a message in my heart clear as day,” Martin wrote in a GoFundMe he started called “Living for God” to continue the effort. “God spoke to me through this feeling and led me to spread his word in everything that I do.”

After the Marcus Pointe Christian School student got the idea, he told his grandmother, Stacey Yates, that he needed help to purchase the supplies and find people in need.

Yates recently drove Dylandin around as he handed out Christmas bags filled with food, water, toiletries, a blanket, and a card that reads, "God Loves You" at the Waterfront Rescue Mission and other places in the area.

"This was all his idea, to take his money that he saved up to buy for people that are underprivileged and give back," Yates said to one of the men Martin was helping in a video posted to Facebook.

"Oh, bless his little heart," he said. "Wow, God bless you. You are an awesome little man. Merry Christmas! Thank you so much!"

Another recipient of Dylandin’s gift, Freddie Olds, who had been homeless for two months, told WEARTV the kind gesture inspired him to pay it forward.

“You wouldn’t think someone would do something like that,” he said. “You want to do the same for someone else.”

Opening Doors, a homeless organization in Pensacola, made Dylandin its ambassador.

“Everybody deserves a little light and happiness in their life, and I hope to make that a reality,” Dylandin said.

A Florida woman was arrested Tuesday after she refused to drop a large piece of concrete – and instead appeared to attempt to throw it at responding officers, body cam footage shows.

Cape Coral Police Department video showed Jessica Blick, 37, on the phone outside a dollar store when officers arrived. It was not immediately clear why she had called authorities and Blick ignored the officers' requests to drop a piece of concrete she was holding in her hand.

When Blick noticed another officer approaching her from behind, she appeared to toss the piece of concrete at the cop who had been talking to her. Blick allegedly threatened to kill one of the officers, too, according to FOX 13.

A Pakistan-born South Florida man has been accused of posting detailed bomb-making instructions to online sites frequented by extremists, including supporters of ISIS, according to a federal complaint unsealed Monday.

Tayyab Tahir Ismail, 33, posted the instructions at least five times between July and September, prosecutors said. He faces up to 20 years in prison if convicted.

According to investigators, Ismail posted messages of support for ISIS and did his own online searches on how to build bombs, though there is no evidence that he actually had live explosives. He also allegedly brought ISIS propaganda publications back to the U.S. from Pakistan when he returned from a trip there last year.

"You are surrounded by methods to hit them. Kill the devil's soldiers without hesitation. Make them bleed even in their own homes," read one message Ismail is accused of sharing online. "There are plenty of methods to attack my brother."

Officials said one of Ismail's posts included step-by-step instructions on building a suicide vest. FBI specialists determined that viable explosives could be built using the techniques Ismail allegedly described.

Ismail was an acquaintance of James Medina, who was sentenced to 25 years in prison last year for plotting to bomb a synagogue and Jewish school center during Passover in 2016. The two lived together while Medina was working on his plot, which was an undercover FBI sting operation using a fake bomb.

"On the day Medina attempted to bomb the synagogue, Ismail learned of Medina's plans to move forward and conduct the attack, but he did not alert law enforcement," the affidavit said.

After Medina's arrest, Ismail surrendered several firearms at authorities' requests, court documents showed. However, he was not charged in that case.

The FBI said it's been aware of Ismail since October 2010, when he allegedly made terrorism threats at a Florida homeless shelter, claiming he was an "Al Qaeda soldier" and would "blow it up." He also responded to an insult from a woman by allegedly saying, "we throw women like her in the ditch."

Ismail was arrested Friday, court records showed, and a Dec. 26 bail hearing has been scheduled.

An 84-year-old Army veteran in Jacksonville, Florida, died after he reportedly developed a gangrene infection in his genitals. Now his family members allege the nursing home where the veteran lived ignored his condition until it was too late.

The vet, York Spratling, began living at the Consulate Health Care of Jacksonville in December 2016 after his health began to worsen and he was unable to live alone, The Naples Daily News reported. In February 2017, Spratling was rushed to a local emergency room and was informed that his genitals had become gangrenous. Gangrene is dead tissue caused by an infection or lack of blood flow.

Doctors there told Spratling – he reportedly had diabetes, a condition which can increase a person’s chances of developing gangrene, according to the Mayo Clinic — and his family that the man required surgery to remove the dead tissue.

The doctor "said he had never seen anything like that before, especially in this day and age,” Derwin Spratling, the veteran's nephew, told the Naples paper. “It really freaked us out.”.

The man died shortly after the surgery, according to the newspaper.

Staffers at the nursing home reportedly told state investigators they “could smell [his ] infection from the door to his room,” the newspaper reported, citing reports. But despite the stench, the staff did not document the infection or tell a doctor until five days later, the newspaper said.

The veteran was allegedly not being bathed, though nursing home staff claimed that Spratling refused showers.

“It’s way past obvious. This is so past obvious that it’s mind-blowing,” Derwin Spratling said of his uncle’s condition.

Investigators later concluded the man’s death was “due to inadequate supervision and medical neglect,” The Naples Daily News reported.

Despite the findings, however, there has reportedly been no action taken against the nursing home by the Agency for Health Care Administration (AHCA), a state agency that regulates nursing homes in Florida, according to the newspaper.

What's more, the investigation into Spratling's condition came after AHCA had cited Consulate Health Care three times in the year before the vet's death, claiming the nursing home did not have “enough nurses to properly care for residents, including showering them,” the newspaper reported.

It was not immediately clear if Spratling's family plans to take legal action.

Consulate Health Care did not respond to Fox News’ request for comment on Saturday.

A Florida woman has been convicted of conspiring with her lover to kill her husband—18 years after he disappeared and she collected $1.75 million in life insurance benefits when his death was ruled an accident.

Denise Williams, 48, reportedly showed no emotion as the verdict was delivered Friday in Leon County after a week-long trial that included details of threesomes and drew comparisons to the film noir classic “Double Indemnity.”

She now faces a mandatory sentence of life in prison after being found guilty of murder and conspiracy to commit murder in the death of her 31-year-old husband, Mike Williams, who vanished Dec. 16, 2000 on a duck hunting trip.

Prosecutors said Denise Williams hatched the murder plot with a man who was her husband’s best friend — and her lover, Brian Winchester.

He became the prosecution’s star witness, testifying that they killed Michael Williams so they could be together and collect on life insurance policies by making the murder look like an accident, according to the reports.

Winchester sold Mike Williams one of those policies, worth $1 million.

Winchester told the jury that plans to make the murder look like a drowning went awry when Michael Williams’ duck-hunting equipment failed to drag him underwater.

He testified that he wound up shooting Michael Williams in the face with a 12-gauge shotgun and then burying the body near a lake, according to reports.

The New York Post reported that Winchester and Denise Willaims carried on their secret relationship until 2005 when they married.

Lynda Meier vanished after leaving her Florida apartment at around 5 a.m. on June 4, 2010. On Wednesday, police may have finally discovered where she ended up.

Human remains were discovered while investigators were searching a Miami Gardens field for Meier, police said Thursday. The medical examiner’s office will have to determine whether the remains belong to Meier, who was 40 years old at the time she disappeared.

“During this investigation, investigators located what appears to be human remains near the area in which Meier was last believed to have been,” Hallandale Beach spokeswoman Ra Shana Dabney-Donovan said in a statement.

A search for human remains in the Miami Gardens area was launched earlier in the week when authorities received a tip from a “source” about a body that had been dumped in a tree preserve, the Miami Herald reported. The remains were discovered in a wooded area between a construction site and a house, Osvy Rivera, a worker at the construction site, told the newspaper.

Meier disappeared in 2010. She had plans to take her mother, who lived in Aventura, to a doctor’s appointment but never showed up to her mom's home, according to the Miami Herald. Surveillance video showed Meier leaving her apartment in Hallandale Beach at around 5:17 a.m. that day. Two days later, her abandoned Cadillac Escalade was discovered near an apartment complex in Miami Gardens, police said.

Police questioned two felons who had contact with Meier, but were never able to link the men to her disappearance, the newspaper reported.

Police also searched an area in Opa-locka in June 2013, but came up empty.

The family of a Florida woman that claims she was left for dead after falling off a motorcycle during a first date filed a wrongful death lawsuit on Friday against the New York man she apparently met on Tinder, reports said Friday.

Jennifer St. Clair, 33, went on a date with Miles McChesney, 34, after meeting on the Tinder dating app, according to the family's lawsuit. They claim he was negligent in her death.

Todd Falzone, the family's attorney, said Friday that McChesney, of Schenectady, N.Y., was visiting a cousin in Fort Lauderdale when he met St. Clair, The South Florida Sun-Sentinel reported.

McChesney rode a 2001 Harley Davidson Road King motorcycle while they were on their date in Delray Beach, the suit read. The pair met with two other couples and visited a few bars in the area, the suit said. The suit claims that McChesney "drank alcohol to the point where he became impaired."

The suit claims that at one point during the date, McChesney, while impaired, "carelessly and negligently operated, controlled and/or maintained" the motorcycle so as to cause St. Clair to be "expelled from said motorcycle into oncoming traffic" on Interstate 95.

"After stopping briefly, but rendering no aid or assistance to Jennifer St. Clair, Defendant, Miles McChesney left the scene," the lawsuit said.

FAMILY OF FLORIDA WOMAN WHO DIED ON FIRST DATE CLAIM SHE WAS LEFT FOR DEAD ON INTERSTATE: REPORT

Falzone told The Sun-Sentinel that the woman could have been hit by as many as nine vehicles.

Some witnesses said they saw a man on a motorcycle standing near the victim's body and then took off, The Miami Herald reported. That storyline matches what authorities said, according to the family.

St. Clair was found dead last Friday around 3 a.m.

Florida Highway Patrol officials said St. Clair's death is being investigated as a traffic homicide, The Herald reported.

The lawsuit is seeking $15,000 in damages from McChesney, Miami's WPLG-TV reported.

McChesney's lawyer released a brief statement to the station.

"I am representing Myles McChesney in regards to an Florida Highway Patrol Investigation. This is a very tragic event. And this is all I am going to say about it at this time," Russell Cormican said.

St. Clair worked as a server in restaurants and lived in Fort Lauderdale with her parents, The Sun-Sentinel reported. Pompano Beach, where her body was found, is about 11 miles north of Fort Lauderdale.

“She was surrounded by a big family who loves her so much,” aunt Amy Gamber told the paper of her niece. “We’re still trying to process all of this.”

A man convicted of viciously stabbing a woman to death during a South Florida burglary 26 years ago was executed Thursday night.

Jose Antonio Jimenez, 55, was put to death by lethal injection and pronounced dead by 9:48 p.m. at Florida State Prison in Starke. The execution was initially set for 6 p.m. but was delayed by a last-minute stay request to the U.S. Supreme Court, which was declined.

Jimenez declined to make any last statements, the Miami Herald reported.

Jimenez was convicted of the 1992 death of Phyllis Minas, 63, during a burglary inside her Miami apartment. Authorities said he was in the middle of burglarizing the residence when Minas came home. She was stabbed eight times.

“Mr. Jimenez has shown no remorse or repentance for his crime,” Minas nephew Alan Partee said in a written statement released by the Florida Department of Corrections after the execution. “His execution will allow closure to a painful memory of the vicious murder … My family hopes he has made peace with himself and to whatever power he may or may not believe in. We pray for his soul and feel justice has been rightfully served.”

During Jimenez's week-long trial in 1994, neighbors said they heard her screaming during the attack and tried to enter the apartment but someone had locked the door.

Fingerprints inside the apartment matched Jimenez, prosecutors said, and a custodian said he saw Jimenez jump from the balcony of Minas’ second-floor apartment.

Jimenez’s attorney’s argued the evidence against him was circumstantial.

In several failed appeals over the years, Jimenez and his lawyers said detectives gave “false, or, at best, misleading testimony.” They also argued several key police reports had been lost.

The request to the Supreme Court for an execution stay asked the court to consider whether Florida’s lethal injection protocol is cruel and unusual punishment and violates the Eighth Amendment.

MAN GETS 9 YEARS IN PRISON FOR SEX ASSAULT ON FLIGHT

After Gov. Rick Scott signed off on the lethal injection for Jimenez, the Florida Supreme Court issued a stay order to consider Jimenez’s claims, including his denial of access to public records, that the state’s drug protocol could cause him harm and that it was cruel to execute him after 23 years on death row.

In October, the court rejected the claims and lifted the order.

Jimenez was the fifth killer executed since Florida added a drug to its lethal cocktails. In 2017, the state included etomidate — a drug intended to induce unconsciousness during executions.

A man who followed what he believed to be his missing brother’s car to a Florida Walmart’s parking lot Thursday led police to the grim discovery of a man’s body inside the trunk, authorities said.

Miami-Dade Police said a man told officers he spotted what he thought could be his missing brother’s white Honda Accord and followed it from Monroe County to the Florida City store. The man had reported his brother missing on Tuesday, FOX Miami affiliate WSVN-TV reported.

Police arrived in the parking lot to find two men and a woman inside the car. Officers said a foul odor coming from the vehicle led to the grisly find inside the trunk, the Miami Herald reported.
